  1. 11. Super-resolution Luminescence Micro-Spectroscopy : A nano-scale view of solar cell material photophysics

    Författare :Aboma Merdasa; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; super-resolution microscopy; Single Molecule Spectroscopy; J-aggregates; perovskites; photophysics;

    Sammanfattning : Optical microscopy is a fundamental tool in a range of disciplines encompassed by the physical and biological sciences. At the dawn of this millennium, a break-through was made in optical microscopy where super-resolution methods emerged and declared imaging beyond the optical diffraction limit a possibility. LÄS MER

  3. 12. Investigation of Neuronal Protein Trafficking at the Molecular Scale

    Författare :Martina Damenti; Ilaria Testa; Clive Bramham; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Endoplasmic Reticulum; Mitochondria; Arc Activity-regulated cytoskeleton-associated protein ; oligomerization; pRESOLFT; STED; event-triggered FCS; DNA-PAINT; STARSS; molecular dynamics simulations; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Neurons are polarized cells that encode information in the nervous system viaelectrochemical connections named synapses. The tuning of synapticconnections is enabled by a plastic protein trafficking system which operates atthe nanoscale to finely tweak the neuronal ultrastructure. LÄS MER

    Sammanfattning : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. LÄS MER

  5. 14. The upper gastrointestinal tract in chronic alcoholics

    Författare :Truls Hauge; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alkaline phosphatase; mucosal bacterial growth; Helicobacter pylori; morphology; upper gastrointestinal endoscopy; chronic alcoholics; upper gastrointestinal tract; gamma-glutamyl transferase; neuropeptides.; Gastro-enterology; Gastroenterologi;

    Sammanfattning : Background: Gastrointestinal symptoms such as dyspepsia, diarrhoea, and nausea are often seen in alcoholics. The causes are not clear. The stomach and upper small intestine are exposed to high alcohol concentrations. LÄS MER

  7. 15. Bioinformatic Methods in Metagenomics

    Författare :Johannes Alneberg; Anders F. Andersson; Lars Arvestad; Nicola Segata; KTH; []
